Sentences with phrase «generation biofuel ethanol»

Further development of our current study would significantly contribute to the production of not only second - generation but also third - generation biofuel ethanol.

Not exact matches

The first - generation biofuel, industrialized, ethanol, is produced from foodstuffs like maize, and thus poses great concern about a possible future shortage of food.

But the problem is that most of the ethanol we have right now is when it is talked about it being a first generation biofuel; that is that ethanol fuel is coming from the fermentation of sugars from crops like corn.

Stock says the debate between agriculture and oil interests over ethanol has been needlessly divisive, and that the EPA under Pruitt should instead turn its focus to «second - generation» biofuels that do not provoke such bitter fights.

Now, Brazil hopes to tap into a new biofuel source: second - generation ethanol, produced from the tough cellulose in plant stalks.

Next - generation biofuels could, unlike corn ethanol, completely replace petroleum - based fuels in the gas tanks of existing cars, trucks, and planes.

For years we've been promised the next generation of biofuels, made from waste cellulose, but we have yet to see it replace corn ethanol.

Some green activists supported mandates for biofuel, hoping they would pave the way for next - generation ethanol, which would use non-food plants.

The authors added, «[O] ur analysis shows that carbon releases from the soil after planting corn for ethanol may in some cases completely offset carbon gains attributed to biofuel generation for at least 50 years.»

«Depending on prior land use, our analysis shows that carbon releases from the soil after planting corn for ethanol may in some cases completely offset carbon gains attributed to biofuel generation for at least 50 years,» they note.

Researchers continue to struggle to develop «second generation» biofuels that they hope will use enzymes to turn cellulose from wood and crop waste into ethanol.

So, more attention and resources are going into the producing of ethanol and other biofuel types from second - generation feedstocks, sometimes known as non-food crops.

With the reputation of first generation biofuels like corn ethanol darkly tarnished, the move is on to develop second - generation biofuels that

The most water - efficient energy sources are natural gas (though we may be just about out of it) and synthetic fuels produced by coal gasification; the least efficient are ethanol and biodiesel — the biofuels just can't catch a break these days, can they?Water use winners and losers The research pair analyzed 11 types of energy sources, including coal, fuel ethanol, natural gas, and oil; and five power generating methods, including hydroelectric, fossil fuel thermoelectric, and nuclear methods; in terms of power generation, Younos and Hill have found that geothermal and hydroelectric energy types use the least amount of water, while nuclear plants use the most.

(Note that the study did not look at first generation biofuels made from tropical crops like sugarcane or sweet sorghum which reduce emissions far more than corn ethanol; for sugarcane ethanol, the reduction is as large as that of cellulosic biofuels, earlier post.)
